The supercomputer ＂Shenwei Taihu Light＂ is the fastest in the world.
On June 19th, at the Global Supercomputing Conference in Frankfurt, Germany, China’s "Shenwei Taihu Light" topped the list of the top 500 supercomputers in the world. Since it came out in June 2016, this is the third time that it has been awarded the "fastest supercomputer in the world", thus achieving "three consecutive championships".
"Shenwei Light of Taihu Lake" was developed by National Parallel Computer Engineering Technology Research Center, using China’s own chip. In the field of supercomputers known as "the heavyweight of the country", "Shenwei" indicates that China’s supercomputing technology has made many key breakthroughs, providing technical means for solving a series of major challenges such as economic and social governance, and has strategic significance for enhancing comprehensive national strength.
How fast is Shenwei? It has three "world first" indicators: the peak performance of the system is 1.25 billion times per second, the continuous performance is 930 million times per second, and the performance-power ratio is 6.05 billion times per watt. It is understood that its one-minute computing power is equivalent to 7.2 billion people around the world using calculators for 32 years without interruption.
Why is this so? It uses 40 computing cabinets and 8 network cabinets for "system operations". Pushing open a cabinet slightly larger than a household double-door refrigerator, four groups of super nodes consisting of 32 computing plug-ins contain 1024 high-performance processors; Each processor is equivalent to the computing power of more than 20 commonly used laptops. The whole "Shenwei Taihu Light" has a total of 40,960 processors, and the speed can be imagined.
More importantly, the central processing unit "Shenwei 26010" of "Shenwei" was designed and produced by China independently, and the whole system realized full localization of the core components. In the past, foreign countries crowded out surveillance and restricted the sale of core parts for China supercomputer research. Nowadays, there are 260 computing cores, billions of transistors and more than 3 trillion calculations per second … … The 25-square-centimeter "Shenwei 26010" has not only become the fastest supercomputer "heart" in the world, but also broke the 30-year foreign core technology blockade and opened the "China Core" era with completely independent and controllable software and hardware.
The speed is ahead of the world, and the application ability is also accelerating. The speed advantage of supercomputing is transforming into the application advantage. Last November, based on "Shenwei Taihu Lake Light", the application project of "Ten Million Approved Expansion of Global Atmospheric Dynamics Full Implicit Simulation" won the highest award in the field of international high-performance computing applications — — The "Gordon Bell Award" fills the gap of China’s supercomputing application in this award.
At a deeper level, "‘ Shenwei Light of Taihu Lake ’ It plays a very important role in China’s scientific and technological innovation and economic development. " Fu Haohuan, deputy director of the National Supercomputing Wuxi Center, said. Relying on the "Shenwei Taihu Light", China completed the numerical simulation of the global 10 km high-resolution earth system with a scale of one million nuclear; Two weeks to complete the routine 10-month calculation of Shanghai drug screening and disease mechanism research … … It is understood that in the past year, "Shenwei" has been involved in 19 application fields such as climate and meteorology, advanced manufacturing, aerospace, high-energy physics, life sciences, etc., supporting hundreds of solving tasks in major national scientific and technological applications, advanced manufacturing and other fields, and completing more than 2 million homework tasks in total.
